GASJSURNER Specification of Letters liatent.

Patented Feb. 25, 1908.

Applieationlfiled December 7. 1907. Serial No. 405.474.

To all whom it may concern:

Be it known that I, FREDERICK C. VEAR- ING, a citizen of the United States of America, and resident of Cincinnati, county of Hamilton, State of Ohio, have invented certain new and useful Im rovements in Gas-Burners, of which the fo lowing is a specification,

The object of my invention is a device for burning either artificial or natural gas by means of which a practically thorough combustion of the carbon of the gas with the oxygen of the air is secured in order that as great a quantity of heat may be had as possible from the combustion of a given quantity of gas. This object is attained by the means described in the specification and illustrated in the accompanying drawings, in which,

Figure l is a view in central section of an ordinary furnace, such as is used for the combustion of fuel and in elevation of a burner embodying. my invention. Fig. 2 is a central sectional view of the burner taken upon line x-x of Fi 1 upon an enlarged scale. Fig. 3 is a deta' view upon an enlarged scale of the deflector which may be used above my burner when it is a plied to a furnace, showing the means emp oyed for inserting it through the furnace door. Fig. 4 is a plan view of the deflector plate shown in Fig. 3.

The burner consists of a housing, A, in the shape of an inverted cup, having upon its interior a diaphragm, a, which forms a shallow combustion chamber, a, between the partition and the closed end, a2, of the cup. Near the lower edge of the cup a series of perforations, a3, is formed in its walls, and between the partition, a', and the end, a2, is also a series of perforations, a4. Diaphragm, a, has a series of down-turned lugs, a5, by which it is secured to the walls of the cup, and in the diaphragm is a series of perforations, a, and a series of perforations, a7, is formed around the edges of the diaphragm adjacent to the walls of the cup.

The closed end, a2, has a central perforation, in which is seated a nozzle, B. The

partition, a, vertically below the nozzle, B, is imperforate. The nozzle, B, is connected to the gas-pipe, C, which is provided with an airemixer, c. Pipe, C, has a horizontal portion, d, which extends through the housing, A, beneath the diaphragm, a, and the mixer, c, is located between the part, c', and the horizontal part, c2, which leads to the nozzle, B. The end, a2, extends beyond the sides of the cup forming a down-turned annular ledge, a8.

In Fig. l, I have illustrated my burner as applied to a hot air furnace intended for burning fuel, such as coal. In this use the housing, A, is placed above the grate, d, and the cock, d', for turning on the gas is located without the furnace, the pipe being led through the ash-pit door, d2, and up through the grate-bars. A deiectorplate,-E, may be placed upon the horizontal pipe, c2, above the bottom, a2. This plate consists of a semi-circular plate, e, having a semi-cylindrical groove, e', along its edge and hinged to it is a segmental plate, e2, which is provided with lugs, e3, which in the horizontal position ofthe plate, @2, project underneath the part, e', to hold the plate, e2, in horizontal alinement with the plate, e. In this position, the width of the dellector, E, is greater than the width of the door, d3, and to insert the deilector through the door, the plate, e2, may be thrown to a vertical position,.such as shown in Fig. 3. The semiecylindrical groove, e', having been made to rest upon the pipe, c2, the part, e2, may be adjusted to its horizontal position.

In operation, gas having been admitted to the pipe, C, and having been ignited in the combustion chamber, a', it is seen that the heat in the combustion chamber will expand the gas in the part, c, of the pipe, so that the gas passing through the mixer, c, will be less dense than the gas at ordinary temperature. A more thorough mixture of the air and gas is had, therefore, at this point.

This mixture of air and gas then passes through the horizontal portion, c2, and is emitted through the nozzle, B. The partition, e, acts as a spreader, as indicated by arrows in F ig. 2, and causes this admixture of air and gas, which is discharged down from nozzle, B, to be thoroughly mixed with air arising through the perforations, a, a7. The combustion of the gas is therefore practically complete as the products escape through the perforations, a4. But, here again, these products are prevented from arising too rapidly to the chimney by the ledge, as, and the defiector, E, so as to complete the combustion before the products reach the chimney.

What I claim is:

. In a burner a housing having its upper end imperforate except for a nozzle opening,

' a nozz a nozzle rojecting downward through the up er en of the housing, a horizontal partition within vthe housing adjacent to the nozzle and forming with the closed end of the housing a shallow combustion chamber, the said combustion chamber having perforations in its wallsand the partition having perforations in it, and a gas-pipe connected to the nozzle whereby the gas is discharged downward through the nozzle, spread by the partition and iniXed with air arising through the perforations in the partitions into the combustion chamber.

2. In a burner a housing having its upper end iin erforate except for a nozzle opening, ie projecting downward through the upper end of the housing, a horizontal partition within the housing adjacent to the nozzle and forming with the closed end of the housing a shallow combustion chamber, the said combustion chamber having perforations in its walls and the partitions having perforations in it and a gas pipe connected to the nozzle whereby the gas is discharged downward through the nozzle, spread by the partition, the pipe having in it a horizontal portion passing through the housing beneath the partition and a rniXer connected to the pipe upon the exterior of the housing between the said horizontal portion and the nozzle.

3. A burner consisting of a housing in the form of an inverted cup with a horizontal external ledge around its top, a perforated artition within the housing forming a shalow `combustion chamber in the top of the housing, theV housing having perforations in its walls below the ledge, a nozzle projecting through the top of the housing and opening adjacent to the partition, and a gas pipe connected to the nozzle whereby gas is discharged downwardly irorn the nozzle, spread by the partition and adrniXed with air arising through thepartition and-the products of combustion escaping through the perforations beneath the ledge are deflected by the ledge.
